GPS screen brightness
I have a Navman Trackfish 6600 and have problems seeing the screen. This weekend, for some reason, the screen seemed to have turned its brightness down so faint it was almost impossible for wife to give me readings. Not having manual with me, could not readjust brightness on water, as couldn't see the screen options!
The second problem is using polarised sunglasses, which not surprisingly requires one to turn head at awkward angles to see screen clearly. My questions are:
1. Is it possible the screen has gone dim by its own accord and if so, is this a sign of a possible problem with the unit?
2. How does one counteract the effect of polaroid sunglasses, other than not wearing them?
